DIESELR Signature CAN Plug (2019-2022 Duramax 3.0L LM2)

The DIESELR Signature CAN Plug for the 2019–2022 3.0L Duramax LM2 is a precision-built interface for the factory CAN bus. It uses OEM-style connectors and pins to integrate into the LM2 harness directly, with no splicing or cutting required. Each unit is fully sealed against moisture, heat, and debris for reliable service in the engine bay. Manufactured in the USA for consistent fit and finish, and backed by a lifetime warranty. ⚡ Engineered to a Higher Standard — Gold-Plated & Salt-Tested Most CAN plugs use standard tin or copper pins. Ours don't. Every DIESELR Signature connector is built with gold-plated pins and validated to a marine-grade corrosion standard — the difference between a connector that lasts and one that fails under real conditions. Gold-plated pins — maximum conductivity for clean signal and power transmission Zero oxidation — unlike tin or copper, gold will not tarnish or corrode in moisture or heat Durability — resists micro-arcing and fretting degradation over time 1,000-hour salt-spray tested (ASTM B117) — the stringent qualification tier used for extreme marine and offshore-grade connections, far beyond the 96–240 hours typical of standard automotive connectors Features OEM-style connector and gold-plated pins for a direct, factory-style fit Fully sealed against moisture, heat, and engine-bay debris No splicing or cutting — clean connection to the CAN bus Manufactured in the USA Lifetime warranty Fitment Engineered for 2019–2022 GM 1500 trucks equipped with the 3.0L Duramax LM2.
